A printing system comprises: a printing unit configured to print an image on a sheet; and a control unit configured to control to perform creasing at a first pressure at a portion, corresponding to an edge of a spine cover, of the sheet on which the printing unit has printed the image, and perform creasing at a second pressure different from the first pressure at a portion of the sheet that corresponds to a hinge.

In a method for manufacturing movable products, at least one substrate to be processed into the product is provided with an identification that is generated from parameter values of the product to be manufactured in accordance with a rule. This rule is so bijective that identical parameter sets always lead to the same product code incorporated into the identification, and that the product parameter set, on which the identification is based, can be reconstructed from the identification at any time.

A bookbinding device includes a control unit for calculating set parameter values for a clamper and a processing unit on the basis of thickness on a book body to be bound, and initially setting the clamper and the processing unit in accordance with the set parameter values. The control unit includes an input unit for receiving an input of a reference parameter value for two or more different book body thicknesses; a function generation unit for generating, on the basis of the reference parameter value, a function for calculating a set parameter value that has been adjusted in accordance with the book body thickness; a parameter calculation unit for calculating, on the basis of the book body thickness, the set adjusted parameter value by using the function; and an initial setting unit for initially setting the clamper and the processing unit in accordance with the set adjusted parameter value.

A method for production of adhesive-bound printed products in a machine belonging to an adhesive-binder line. To change over from one job under production to a following job, supplied printed products of the following job are detected via a barcode and stopped prior to being fed into the machine of the adhesive-binder line. Remaining printed products of a preceding job are moved and fully processed through individual processing stations of the machine while the printed products of the following job remain in a waiting position in front of the machine. After completing the last printed product of the preceding job, an empty withdrawal of covers stored in a cover deposit and belonging to the following job is initiated until it is ensured that the stored covers are available for the printed products of the following job. After determining that a withdrawn cover securely matches the printed products of the following job, stopped printed products of the following job are released with a main control and fed into the machine for being processed via the individual processing stations.

An end paper arrangement and method for forming the front and back end paper of a book wherein the end paper arrangement comprises an inner sheet and outer sheet which are fastened on one side against each other over at least one area so that an unfastened area remains between the fastened areas. The unfastened area forms a tunnel for the spine of the book. On that side of the inner sheet which is opposite to the fastened side there is an adhesive surface on both edge parts, and there is an adhesive-free area between the adhesive surfaces. On the side of the outer sheet which is opposite to the fastened side, there is an adhesive surface on both edge parts, and there is an adhesive-free area between the adhesive surfaces. The method performs the assembly set forth in the arrangement.

Apparatus for use with a trimmer to produce a plurality of books having different trim sizes are described. In a described example, a trimmer for use with a bindery system includes a cutting surface and a first movable backstop adjacent the cutting surface to be engaged by a first book. Additionally, the trimmer includes a second movable backstop adjacent the cutting surface and spaced from the first movable backstop. The second movable backstop is to be engaged by a second book. Further, the trimmer includes a cutter movable relative to the cutting surface to cut a face of the first book to form a book having a first size and to cut a face of the second book to form a book having a second size different than the first size.
